About Heart Rate Zones Many athletes use heart rate zones to measure and increase their cardiovascular strength and improve their level of fitness. A heart rate zone is a set range of heartbeats per minute. The five commonly accepted heart rate zones are numbered from 1 to 5 according to increasing intensity. Generally, heart rate zones are calculated based on percentages of your maximum heart rate. Fitness Goals Knowing your heart rate zones can help you measure and improve your fitness by understanding and applying these principles. • Your heart rate is a good measure of exercise intensity. • Training in certain heart rate zones can help you improve cardiovascular capacity and strength. • Knowing your heart rate zones can prevent you from overtraining and can decrease your risk of injury. If you know your maximum heart rate, you can use the table (Heart Rate Zone Calculations, page 14) to determine the best heart rate zone for your fitness objectives. If you do not know your maximum heart rate, use one of the calculators available on the Internet. Some gyms and health centers can provide a test that measures maximum heart rate. The default maximum heart rate is 220 minus your age. Setting Your Heart Rate Zones Before the device can determine your heart rate zones, you must set up your fitness user profile (Setting Your Fitness User Profile, page 10). You can manually adjust the heart rate zones according to your fitness goals (Fitness Goals, page 8). 1 Select Setup > Fitness > HR Zones. 2 Enter the maximum and minimum heart rate for zone 5. The maximum heart rate for each zone is based on the minimum heart rate of the previous zone. For example, if you enter 167 as a minimum heart rate for zone 5, the device uses 166 as the maximum rate for zone 4. 3 Enter your minimum heart rate for zones 4-1.
